BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a wearable electronic device, and more particularly to a wearable electronic device with a detachable power unit.

2. Description of the Prior Art

With the expansion of the application range of wearable electronic devices, the function is becoming more and more powerful, and the use time continues to grow, however, the acceptable size and weight of the battery in the wearable electronic device are often limited, thus limiting the capacity of the battery. As a result, the battery capacity of the wearable electronic device is often unable to meet the needs of large or long periods of use. In the face of this situation, the wearable electronic device must use external power source to replenish the electricity in order to continue to perform the function.

There are two kinds of external power sources: fixed (wired) power supply and mobile (portable) power pack. Fixed power supply includes wall outlet and electronic equipment with USB and Lightning™ port, such as, desktop computer, notebook computer, tablet computer and so on. Lightning™ is the exclusive transmission interface specification designed and manufactured by Apple Inc. Mobile power pack is usually a rechargeable secondary battery. The fixed power supply can be charged only when the wearable electronic device is removed from the user. As for the mobile power pack, although it can be carried with you, it can only be placed in handbags, backpacks, travel bags and other personal belongings. When needed, it can be taken out and connected to the wearable electronic device through a connecting line. It can not be directly attached to the user to transmit power to the wearable electronic device, so it is not convenient to carry and use the mobile power pack.

On the other hand, since the wearable electronic device is widely used for health management, such as, detecting heart rate, blood pressure, blood oxygen, sleep state, and so on, it is necessary to be worn for nearly 24 hours for continuous detection. However, for safety and other factors, the wearable electronic device must be removed when charging and cannot be detected during charging.

The present invention mitigates and/or obviates the aforementioned disadvantages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1A and 1B, a wearable electronic device 100 in accordance with a first embodiment of the present invention comprises a body 101 having a first battery 110 to supply the power required for the operation of the body 101. The body 101 also includes a port 111 and two joint portions 112. The port 111 is disposed at the bottom of the body 101 and is electrically connected to the first battery 110. The joint portions 112 are formed at both sides of the body 101. The function of the port 111 and the joint portions 112 is left to be described later.

The wearable electronic device 100 further comprises a band 102 for attaching the body 101 to a user. The band 102 may be made into a long strip by materials such as fluoroelastomer, leather, nylon ribbon, etc., so that the band 102 is flexible and surrounds the wrist, arm, chest, waist, leg, neck or head of the user. Both ends of the band 102 use known techniques, such as magnets, buckles, Velcro™ etc., so that the wearable electronic device 100 can be removably attached to the user. Since the technique of combining both ends of the band 102 with each other is conventional, it is unnecessary to further explain.

The band 102 has a bearing area 120 in the middle of its length to load the body 101. The middle of the bearing area 120 is defined with an aperture 121, which enables a sensor 113 carried by the body 101 to detect the heart rate, blood pressure, blood oxygen, sleep state, etc., of the user through the aperture 121, so that the user do not need to wear other external sensors for health management.

The band 102 also includes two wings 122 connected to both sides of the bearing area 120. A free end of each wing 122 is formed with a joint 123 that is engaged with the joint portion 112 of the body 101. The joint portions 112 shown in the figure are dovetail grooves, so the joints 123 are dovetail joints, which are combined with each other by tenon technology, and other known techniques, such as pin joint, may also be used, without the limitation of the embodiments of the accompanying drawings.

The band 102 further includes a connector 124 and a set of first conductors 125. The connector 124 is disposed on the bearing area 120 and is connected to the port 111 when the body 101 is properly installed in the bearing area 120, so as to make the body 101 electrically connected to the band 102. The first conductors 125 are disposed on the band 102 and are electrically connected to the connector 124. The port 111 and the connector 124 shown in FIG. 1B are illustrated by Garmin® commodity exclusive transmission interfaces, and other types of transmission interfaces can also be used, without the limitation of the embodiments of the accompanying drawings.

Another important part of the invention is that the wearable electronic device 100 includes a belt 103 that is a detachable power unit having one or more second batteries 131, an input port 130 and a set of second conductors 132 electrically connected to the second battery 131. The second battery 131 is flexible to be bent along with the belt 103, or, as shown in the figure, the belt 103 can be freely bent without the influence of the second battery 131 by using a plurality of non-flexible batteries. The input port 130 is used to connect an external power source, such as, wall outlet, mobile power pack, or another electronic device, such as, desktop computer, notebook computer, tablet computer, smart phone, and so on, so as to charge the second battery 131. The second conductors 132 are disposed on the belt 103, and the first conductors 125 and the second conductor 132 have mutually attractive magnetism, or make a snap button that can be fastened to each other, so that the belt 103 can be removably attached to the outer surface of the band 102. At the same time, an electrical connection is generated between the band 102 and the belt 103. The electricity of the second battery 131 is transmitted to the first battery 110 through the second conductor 132, the first conductor 125, the connector 124 and the port 111, so as to replenish the electricity consumed by the first battery 110 and improve the endurance of the wearable electronic device 100. Moreover, when the belt 103 is removed, the power consumed by the second battery 131 can be replenished by an external power source (not shown) connected to the input port 130, so that the wearable electronic device 100 can still be worn for 24 hours while charging, regardless of the site and no time limit, at any time to master the information. Other designs in which the belt 103 can be freely assembled to and disassembled from the outer surface of the band 102, and the electrical connection can also be adopted, are not limited by the magnet or the snap button.

The belt 103 further includes an output port 133 electrically connected to the second battery 131, so that the second battery 131 can synchronously or separately supply power to another electronic device connected to the output port 133, such as, smart phone, smart watch, etc., when the belt 103 is removed. The body 101 may also transmit data with another electronic device via the output port 133. The input port 130 and the output port 133 can be any type of transmission interface, such as, USB port, mini USB port, micro USB port, Lightning™ port, miniaturized Lightning™ port, and so on.

In addition, as shown in FIG. 2 (second embodiment), a wearable electronic device 100 a comprises a body 101 a having a magnetic port 111 a, and a band 102 a includes a magnetic connector 124 a, so as to replace the port 111 and the connector 124 of the first embodiment respectively. The second embodiment is exactly the same except that the transmission interface is different from the first embodiment, therefore, the same parts of the second embodiment are marked with the same reference sign, and the previous description of the first embodiment is also applicable to the second embodiment and will not be described again. Such a simplified description will also be presented in various embodiments of the present invention.
